Overview

• New Jersey declared a state of emergency ahead of the coastal storm, with forecasts calling for wind gusts up to 60 mph, surges near 3 feet and large waves that could produce major coastal flooding from Long Island to the Jersey Shore through Monday’s high tides.
• The coastal low is keeping showers and gusty winds from the Carolinas to New England into Monday, with local advisories for coastal flooding and rough surf, before drier, cooler weather arrives for most locations starting Tuesday.
• California faces a potent Monday–Tuesday system with widespread rain and isolated thunderstorms, flood watches across several regions, and winter storm warnings in the Sierra where higher elevations could see up to 3 feet of snow and travel restrictions.
• Forecasters warn that the cold-core low could trigger downpours, small hail and a few strong cells, raising flash-flood and debris-flow risks near recent wildfire burn scars from the Central Coast through Los Angeles.
• Moisture from the remnants of Priscilla and Raymond is enhancing showers in parts of the Southwest, though many inland areas nationwide are expected to turn drier by midweek.
